Thanks for the compliments everyone.
When making the vacuum manifold I was considering multiplying it, but came to the unfortunate conclusion that it makes no business sense at all. It takes too long to make and would just be too pricy.
However the raw material is cheap, so I’ll get some material and when or if I have absolutely nothing better to do, I’ll make 5 units (3 with 4 outlets and 2 with 5 outlets) and offer them for sale for $25ea, when or if they get done.
Hosrom, the functional vacuum diagram remains the same, however the Y-connectors are eliminated and the lines are extended to the manifold.
84black944, anodization is for aluminum, this is brass, which might benefit from a clear-coat to prevent dulling oxidation. However I am not sure which clear-coat will stick.
Todd, I do feel a very slight improvement in the throttle response.
Darius, setting up and justifying a proper flow/suction test could be quite complicated. I think a dimensional analysis (cross-section areas in the flow path) would suffice and will post that in a few days.
Macnewma, the (hard plastic) vacuum lines are new from the local dealership (and my mechanic, Joe Schneider). It is a Mercedes part.
Pink?? … Maybe my intake manifold looks pink on a CRT monitor in need of adjustment, but the color is nothing less than ... get this … “HiPerCrystal™ Raspberry” found here .
NZ, the water is flowing again, now at a rate the engine really likes. Since I have an unknown headgasket and am temporarily tired of wrenching, the boost is kept at 19 psi max. My modified OEM wastegate drops the boost to 17 psi @5000 rpm, but picks it up to 18psi @ 6000 rpm and yes, still with a K26-6.
When I get time I’ll start a thread on that, meanwhile here is a quick teaser picture with a new water rail running opposite the fuel injectors.

Hey Laudst sorry didn't mean it in a picky way ...just was thinking of tests to see the suction flow of each..I don't know why but 4 seemed/felt to me to be of better harmonious flow than 5...I would like to buy one from you Laudst..$ 25? Sold!!!!.
and your intake is cool man..is a 150 psi pump enough to drive 4 nozzles? and how to you controll it's delivery?

To anyone not getting one of Laust's 5 manifolds, this may be of interest to you:

I may look into it, if it meets the rennlist approval.
